The aim of this study is to investigate the association between intraplaque hemorrhage (IPH) detected by non-contrast magnetic resonance imaging (MRI) of the carotid artery in routine clinical practice and ipsilateral acute ischemic events. The investigators' overarching aim is to determine whether this sequence aids the diagnostic work-up of stroke patients. For this purpose, the investigators set up a prospective single-center longitudinal observational study with one year follow-up. In addition, this study will analyze retrospectively obtained data collected through clinical routine.
